+1 Nintendo Land - Best display of the gamepad and amazing with 5 players. Attraction Tour is aaaaamazing.
+1 Super Mario Bros U - HD Mario is amazing. The only bad thing is the fact is that the game is rather short and you cant use Mii's in the Story mode. Defeats the Mario and U idea. Still a Recommended Game. Maybe the Future DLC will make it better.
+1 Call of Duty - BLOPS2 - Storyline is not as great as the first. Multiplayer and Zombie mode are amazing. Ability to use Classic Controller, WiiMote + Nunchuck, Classic Pro Controller, Gamepad (Great for two players), and Zapper Accessory. A load of controller arsenal. On the fly switching with the GamePad is a +1.
+1 Fifa 13 - Not as good as PS3 or xBox 360. Many thing missing.

So in which order to I really recommend:

1) Nintendo Land (Highly)
2) COD BLOPS2 (Great Choice)
3) New Super Mario Bros U (Amazing but short lived, Maybe DLC will make it better) [With DLC, I would switch this with BLOPS 2.]
4) Fifa 13 (Not as much)

I really had my doubts whether to add this or not (after all, you can't properly do a quality/cost check on how good it is), but in the end, I added this (there wasn't a rule not to...and I must admit I like that demo more than nano assault neo thus far).

However, keep this in mind: this vote is not a vote for the full game (you'll have to recast it after playing the full version for an hour ). And if the demo gets pulled off the eshop, I'll also remove it from this list.

I've played this game countless of hours and In my opinion it's the best 3rd party Wii U game out right now.
The game is absolutely fluid, a steady frame rate of 60 fps. It's the Tekken game you all love, but with added features
Including
- All DLC from start
- New modes
- Nintendo costumes
- And miiverse functionality

This game is underrated for being on Wii U, but it's a must buy if you enjoy fighters.
For what it's worth, you get a good value!

I bought Mighty Switch Force HD and it's basically the exact same game as the 3DS game but with higher quality graphics. So if you already own the 3DS game, it's money thrown in the sea. Also I recommend the 3DS version over the HD version because it actually has the 3D.
